What about something like that Aluma(sp?) seal stuff? Not sure if you can use as a temp fix?? Maybe, a small amount wouldn't clog the radiator, IDK if you can even use on bikes?? I remember you saying you smelled something. I think all that mud made a good seal last weekend, just leave it on. If it's a slow leak, best be carrying extra water if you decide to putt around before you get it fixed/looked at.
